ADP5134 - 1200 mA Buck Regulators and Two 300 mA LDO Regulators

Description

The ADP5134 combines two high performance buck regulators and two low dropout (LDO) regulators.

It is available in a 24-lead 4 mm × 4 mm LFCSP.

The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space.

Features

  • Main input voltage range of 2.5 V to 5.5 V Two 1200 mA buck regulators and two 300 mA LDO regulators 24-lead, 4 mm × 4 mm LFCSP package Regulator accuracy of ±1.8% Factory programmable or external adjustable VOUTx Precision enable pins for easier power sequencing Factory selectable power-good pin 3 MHz buck operation with forced PWM and automatic PWM/PSM modes BUCK1/BUCK2: output voltage range from 0.8 V to 3.8 V LDO1/LDO2: output voltage range from 0.8 V to 5.2 V LDO1/LDO2: input voltage range.
